Coma at the end of each eanswer of my checkbox

I have a simple query for a list using checkbox :

<cfloop query="getlist">

#thingstodo# : <input type="checkbox" name="thingstodo" value="<br/>#thingstodo#"> <p>

</cfloop>

So it will apear like this :

Some list of things to do 1 : <input type="checkbox" name="thingstodo" value="<br/>Some list of things to do 1"> <p>

Some list of things to do 2 : <input type="checkbox" name="thingstodo" value="<br/>Some list of things to do 2"> <p>

Some list of things to do 3 : <input type="checkbox" name="thingstodo" value="<br/>Some list of things to do 3"> <p>

Some list of things to do 4 : <input type="checkbox" name="thingstodo" value="<br/>Some list of things to do 4"> <p>

My problem is it adds a coma at the end and this is how it looks in the database :

<br/>Some list of things to do 1,<br/>

Some list of things to do 2,<br/>

Some list of things to do 3,<br/>

Some list of things to do 4,<br/>

Some list of things to do 5,<br/>

I tryed using replace before i send it in the databse but i think i'm doing it wrong plus some of the text in the list might have a coma in it so this might not be the answer:

<cfset thingstodo = Replace(thingstodo, ",","","ALL")>

Thanks for your help
